and defines a tube conduit 206. The primary cylindrical tube 200
defines a primary support 208 for terminating displacement and
supporting the platform 140 in the elevated position 160 upon the
primary cylindrical tube 200 abutting the lower end 82 the first
arm 80 and the upper end 94 of the second arm 90. In addition, the
primary cylindrical tube 200 defines a primary shield 209 during
displacement of the platform 140 from the elevated position 160 and
in the non-elevated position 170. The primary shield 209 prevents
foreign objects from entangling with the primary spring 180.
As shown in FIG. 20, the primary spring 180 applies an upper
contraction force 230 for maintaining engagement between the
primary cylindrical tube 200 with the lower end 82 the first arm 80
and the upper end 94 of the second arm 90 and resisting the
displacement of the platform 140 from the elevated position
160.
As best shown in FIGS. 4, 10, 12, 16, 20 and 21, a secondary
cylindrical tube 210 encircles the secondary spring 190. The
secondary cylindrical tube 210 extends between an upper tube end
212 and a lower tube end 214 and defines a tube conduit 216. The
secondary cylindrical tube 210 defines a secondary support 218 for
terminating displacement and supporting the platform 140 in the
elevated position 160 upon the secondary cylindrical tube 210
abutting the lower end 102 of the third arm 100 and the upper end
114 of the fourth arm 110. In addition, the secondary cylindrical
tube 210 defines a secondary shield 219 during displacement of the
platform 140 from the elevated position 160 and in the non-elevated
position 170. The secondary shield 219 prevents foreign objects
from entangling with the secondary spring 190.
As shown in FIG. 20, the secondary spring 190 applies an upper
secondary contraction force 230 for maintaining engagement between
the secondary cylindrical tube 210 with the lower end 102 the third
arm 100 and the upper end 114 of the fourth arm 110 and resisting
the displacement of the platform 140 from the elevated position
160.
A primary channel 300 is coupled to the primary side wall 20 and
receiving the lower end 82 of the first arm 80 and the lower end 92
of the second arm 90 for guiding the first arm 80 and the second
arm 90 between the elevated position 160 and the non-elevated
position 170. A secondary channel 302 is coupled to the secondary
side wall 22 and receiving the lower end 102 of the third arm 100
and the lower end 112 of the fourth arm 110 for guiding the third
arm 100 and the fourth arm 110 between the elevated position 160
and the non-elevated position 170. Preferably, the primary channel
300 and the secondary channel 302 define a generally U-shaped
cross-section 304.
As best shown in FIG. 11, a primary stop 310 is coupled to the
primary side wall 20 for terminating displacement and supporting
the platform 140 in the non-elevated position 170 upon the primary
stop 310 engaging with the second arm 90. As best shown in FIG. 10,
a secondary stop 312 is coupled to the secondary side wall 22 for
terminating displacement and supporting the platform 140 in the
non-elevated position 170 upon the secondary stop 312 engaging with
the fourth arm 110. Preferably, the primary stop 310 and the
secondary stop 312 includes a pin 314, screw or other rigid
structures.
The platform 140 may include a platform handle 316 coupled to the
front edge 150 of the platform 140. The platform handle 316 assists
in grasping the platform 140 and facilitating the displacement of
the platform 140 between the elevated position 160 and the
non-elevated position 170.
The case 10 may further include a lower case padding 320 positioned
adjacent to the base wall 14 of the lower case 12. The lower case
padding 320 may include a primary lower case padding 322 and a
secondary lower case padding 324. The primary lower case padding
322 and the secondary lower case padding 324 are position adjacent
to the primary side wall 20 and the secondary side wall 22
respectively. The lower case padding 320 defines a supporting case
padding 326 for supporting a lower object 360. The primary lower
case padding 322 and the secondary lower case padding 324 define a
storage chamber there between and below the lower object 360. In
addition or alternatively, a side case padding 328 may be
positioned between the primary lower case padding 322 and the
primary side wall 20 and between the secondary lower case padding
324 and the secondary side wall 22. The primary lower case padding
322 and the side case padding 328 construct a primary general
L-shaped pad. The secondary lower case padding 324 and the side
case padding 328 construct a secondary general L-shaped pad. The
side case padding 324 distances and cushions the lower object 360
from the primary channel 300, the first arm 80, the second arm 90,
the secondary channel 302, the third arm 100, and the fourth arm
110.
An intermediate case padding 330 may be positioned between the
lower object 360 and the lower surface 144 of the platform 140.
Preferably, the height of the lower case padding 320 and the height
of the intermediate case padding 330 is such that the lower case
padding 320 and the intermediate case padding 330 are compressed
against the lower object 360, when the platform 140 is positioned
in the non-elevated position 170. The compression of the lower case
padding 320 and the intermediate case padding 330 assists in
preventing displacement of the lower object 360 relative to the
case 10.
An upper object 370 is positioned on the upper surface 142 of the
platform 140. An upper case padding 332 may be positioned between
the upper object 370 and the base wall 32 of the upper case 30.
Preferably, the height of the upper case padding 332 is such that
the upper case padding 332 is compressed against the base wall 32
of the upper case 30 and the upper object 370. The compression of
the upper case padding 332 assists in preventing displacement of
the upper object 370 relative to the case 10.
More specifically, the base wall 14 of the lower case 12 and the
base wall 32 of the upper case 30 compresses the lower case padding
320, the intermediate case padding 330 and the upper case padding
332 for securing the lower object 360 and the upper object 370
relative to the platform 140 with the upper case edge 46 of the
upper case 30 positioned adjacent to the lower case edge 26 of the
lower case 12 for enclosing the platform 140 in the non-elevated
position 170.
The platform 140 may include one or more wire apertures 340
positioned generally adjacent to the rear edge 152. The wire
apertures 340 receives an electrical conduit 342 extending between
the lower object 360 and the upper object 370. The wire apertures
340 serve as a wire restraint and organizer during use of the lower
object 230 and the upper object 370 in the elevated position 160,
during transitioning the platform 140 between the elevated position
160 and the non-elevated position 170 and during the platform 140
positioned in the non-elevated position 170.
The upper surface 142 of the platform 140 may also include a
non-skid layer 350. The non-skid layer 350 may include a polymeric
material for increasing the coefficient of fiction between the
platform 140 and the upper object 370 and for preventing
displacement of the upper object 370 relative to the platform 140.
In addition, the platform 140 may further include a fence 380
coupled to the front edge 150 of the platform 140. The fence 380
assists in preventing the upper object 370 from being displaced
over the front edge 150 of the platform 140.
As shown in FIGS. 21 and 23, the case 10 may be utilized for
transporting the lower object 360 and the upper object 370. The
lower object 360 and upper object 370 may include a lower
electrical component 362 and an upper electrical component 372
respectively. More specifically, the lower object 360 may include a
DJ sound control system 364 and the upper object 370 may include a
computer 374. The positioning the platform 140 into the elevated
position 160 provides a convenient orientation of the computer 374
relative to the DJ sound control system 364 in order to
simultaneously view and control both components 364 and 374.
